Question

What is LINQ to events a.k.a RX Framework aka the Reactive Extensions in .NET 4.0 (but also available as backported versions)?

In other words, what

Answer 1

I think the essence of the RX is changing the angle with which we look at information. Naturally, every piece of information is a result of some process, which takes place in the time-space continuum. Traditional approach works with the projection of the process to the "current" time plane, losing the details of the time dimension as the result.

RX works with the projection to some other dimension, capturing the time component as well, so it is no wonder LINQ to RX is a superset of the regular LINQ.
